Looking for some real feedback

So, a little while ago, I bought a Canaan Avalon 1246 miner from CoinMiningCentral. I opted for the best model they had and thought I got a decent deal. Fast forward to now and I've got my order, kinda. They sent me a Canaan Avalon 1166 Pro instead of the 1246 I actually ordered. CoinMiningCentral is telling me the 1166 Pro is basically the same thing, same hardware and all that, and that it performs at the same hashrate as the 1246. Honestly, I’m not buying it. When I placed my order, there was about a $500 price gap between the two models. They admit they sent me the 1166 Pro but can't understand why I'm not thrilled about it. What do you all think about this situation? Sam

I'd ask for the difference in price to be refunded. They aren't exactly the same. Not sure which model you ordered and what model you got but the 1246 is 38J/TH and the 1166 Pro is 42J/TH so you are going to burn more energy to get the same performance out of the 1166 Pro. Also isn't the 1246 like 90TH/s and the fastest 1166 Pro is 81TH/s so it doesn't seem they are at all equivalent.

Hi, @Qasamm I saw Coinminingcentral's offers - 1246@6K GBP and 1166Pro@5.5K GBP. Pls refer to "https://www.bilibili.com/read/cv10355015" and google translate yourself, thus you can see some details - 1. "Avalon attaches great importance to the safety of the machine, has upgraded the machine's firmware, strengthened the machine's anti-tampering mechanism, and built an AI chip K210 on the machine's main control board. It analyzes the fluctuations of computing power through intelligent algorithms, adjusts the fan speed, and identifies potential network attacks and loopholes, thereby stabilizing the computing power within a reliable range and preventing the loss of computing power. Currently only one can achieve this level of security." 2. "Avalon’s new A1246 model is only one month away from the release of the A1166Pro. The recent intensive release of Jiaan is also to meet customer demand for models with large computing capabilities as soon as possible." Sounds like A1246 basically is an A1166 Pro + K210 AI chip in the control board, achieving some 41>38J/TH, like a vendor-provided HW minor upgrade, similar effects to Braiin/Vnish. _______________________________ In short, it's better you ask the UK's Coinminingcentral to at least refund you the 500 GBP difference in price, because there is a little difference - although in terms of Hash power, their basic idea is not too wrong. Coinminingcentral's Director is Mr. Gavin Finder(gavin@coinminingcentral.com). Perhaps you can email him directly. _______________________________ I am from ICI, who sells and services Enterprise IT products since 2007, and Crypto miners this year.

Thank you all for your input. I'm asking for a refund of the difference. I will update all when I hear back.
